Question

solve the system of linear equations graphically 3x +y-5=0; 2x-y-5=0​

Answer 1

Answer:

Step-by-step explanation:

3x + y =5

2x- y = 5

5x      = 10

x=2

6 +y =5 (subsituting value of x)

y=-1

Answer 2

3x+y=5...eq 1

2x-y=5 eq 2

taking eq 1we get

x=5-y/3

put this value in eq w

we get

2*(5-y/3)-y=5.

10-2y/3-y=5

-5y=-15

y=3

put this value of y in x

you will get 2/3
